This paper studies the impact of changes in the external balance of Pakistan. We explain why the economic growth achieved during the past decade was highly dependent on improvements in the external balance. Between 2001 and 2007, Pakistan benefited from an increase in remittances, foreign assistance from bilateral and multilateral sources, and a relatively stable exchange rate. After 2007, this performance came under pressure from external price shocks. The rise in the import prices of petroleum, raw materials and other manufactured goods has the potential to reduce the country’s growth performance, impacting the competitiveness of the economy and threatening the gains achieved during past years. We integrate a computable general equilibrium (CGE) model with a microsimulation model to study the effects of changes in foreign savings and import prices faced by Pakistan. An increase in foreign savings leads to an increase in imports and a decrease in exports. The main sectors facing a decline in exports are textiles, leather, cement, and livestock. In this simulation food and oil prices decline and the factors of production that gain are agricultural wage labor and nonagricultural unskilled wage labor. The increase in import prices of petroleum or industrial raw material leads to a reduction in exports. In this simulation the crop sector is negatively impacted and returns to land and profits to farm owners increase, showing a change in favor of agricultural asset owners, while poverty and inequality increase.

A simultaneous-equations model was used to capture the supply and demand functions for Pakistan’s wheat sector at the national level. This model reflects the fact that Pakistan’s domestic wheat supply is priceresponsive and positively affected by the use of nutrient fertilizers. While price appears to be a statistically significant factor on the supply side, it is statistically insignificant on the demand side. Population size appears to be very significant in determining wheat demand. The wheat import supply seems to be influenced by the current world wheat price, current world wheat supplies, Pakistan’s domestic consumption in previous years, and domestic supply in previous years. We recommend that policymakers allow market forces to play a role in the wheat economy in a way that protects producers from adverse market conditions. The availability of various nutrient fertilizers should be central to policies on future inputs use. Work is also needed on wheat alternatives so that the country’s dependence on wheat is eased as much as possible.

This study tests the semi-strong form of market efficiency by investigating the reaction of stock prices to dividend announcements. It analyzes cash, stock, and simultaneous cash and stock dividend announcements of 79 companies listed on the Karachi Stock Exchange from July 2004 to June 2007. Abnormal returns from the market model are evaluated for statistical significance using the t-test and Wilcoxon Signed Rank Test. The findings suggest negligible abnormal returns for cash dividend announcements. However, the average abnormal and cumulative average abnormal returns for stock and simultaneous cash and stock dividend announcements are mostly positive and statistically significant.

In many countries, capital markets are often served by multiple stock exchanges, typically with one national or dominant exchange and several regional or satellite exchanges. While multiple exchanges create a competitive landscape, they also lead to fragmented liquidity and diseconomies in operations. This paper examines the role of the Lahore Stock Exchange (LSE) in comparison with the country’s dominant exchange, the Karachi Stock Exchange (KSE), in four areas: (i) market efficiency in processing information, (ii) transaction costs, (iii) contribution to price discovery, and (iv) market integration. A comparative analysis of the exchange performance indicates the two exchanges to be at par in terms of informational efficiency and transaction costs. There is evidence of informational linkages and interdependencies between the two exchanges; the LSE appears to contribute to price discovery and competes to an appreciable extent. Against the background of proposals to merge the country’s three stock exchanges, a major consideration in evaluating public policy is the relative performance of the LSE and its viability as an effective competitor. Eliminating inter-exchange competition by merging the stock exchanges is predicted to lead to higher transaction costs, lower incentives for regulatory compliance, and diminished motivation for promoting capital market development.

This paper analyzes trade among and the convergence of per capita income for India, Pakistan, Bangladesh, and Sri Lanka. The extent of trade and its relationship with the magnitude of income convergence is studied among these countries and their trading partners. We use intra-trade convergence and the difference-in-differences approach for the estimations. The results demonstrate that an increase in trade between the groups decreases the per capita income differential. Our results suggest that trade liberalization policies could be effective in achieving convergence. More importantly, we find that the per capita income of our source countries converged more rapidly under post-liberalization regimes than pre-liberalization regimes.

This paper analyzes a range of host country characteristics that determine foreign direct investment (FDI) flows to developing countries, using panel data on 72 countries for the period 1970-2008. Keeping in view the endogeneity problem of the chosen host country’s characteristics, the model is estimated using the General Method of Moments (GMM) technique. The analysis shows that gross domestic product (GDP), economic growth, and per capita income positively affect FDI—a result consistent with the market-seeking behavior of multinational corporations (MNCs). Furthermore, we find that remittances have a significant and positive impact on FDI. On the other hand, inflation and the balance of payments deficit have negative effects on FDI. MNCs are attracted to host countries that are outward looking and follow trade-promoting policies. This is confirmed by the positive effect of openness on FDI flows to developing countries. The study also finds that the effect of military expenditures on FDI is negative and significant. Finally, our analysis finds that the real exchange rate has a significantly negative impact on FDI.

This study examines the technical, allocative, and economic efficiencies of the cotton-wheat farming system in Punjab, Pakistan. It also investigates the determinants of these efficiencies using a non-parametric data envelopment analysis (DEA) technique. Technical, allocative, and economic inefficiency scores are separately regressed on socioeconomic and farm-specific variables to identify the sources of inefficiency using a Tobit regression model. The mean technical, allocative, and economic efficiencies calculated for the system were 0.87, 0.44, and 0.37, respectively. Our results indicate that years of schooling and the number of contacts with extension agents have a negative impact on the inefficiency of cotton-wheat farming in Punjab.

This paper examines the global competitiveness of Pakistan’s fruit exports (dates, mangoes, and oranges), using revealed comparative advantage (RCA). It also analyzes domestic consumption trends among selected fruits grown by major exporters. Our results indicate that Pakistan has a comparative advantage in fruit exports. Comparing the movement in comparative advantage indices for Pakistan with those of its main exporters/competitors demonstrates that Pakistan has a relatively high comparative and competitive advantage in the production of dates and mangoes. The increasing trend of competitiveness in Pakistan indicates that there is potential for higher growth; given that fruit exports are a potential source of higher exports earnings, there is a need to strengthen competitiveness in this sector.

The objective of this paper is to highlight the use of income tax revenue as an indicator of regional development in Pakistan. Initially, we identify a dramatic shift in income tax revenue trends at the provincial level for the period 1992/93 to 2005/06. We develop a simple model of income tax revenue and estimate the relationship between growth of income tax revenue and gross regional product (GRP). Based on the estimated relationship, Punjab appears to have been the fastest growing province during the 1990s, while Sindh shows the greatest level of dynamism in the current decade. This is attributed to high growth rates, especially in large-scale manufacturing during the period, which has a larger sectoral share in Sindh’s economy.

In April 2009, the Centre for Research in Economics and Business (CREB) of the Lahore School of Economics hosted the Fifth Annual Conference on the Management of the Pakistan Economy on the theme, “Growth, Trade and Development.” The Centre’s Director, Naved Hamid, invited a number of prominent speakers including academics, economists, current and former government officials, and other experts to present a combination of research and policy papers, which can be broadly grouped under two major headings: i) Pakistan’s Growth and ii) Trade and Development in Pakistan. These topics were selected because of their timeliness, given the increasing macroeconomic pressures facing the country, in particular those arising from the exchange rate and inflation, and the impacts on poverty that could result. The papers presented at the conference are summarized below:

This paper uses Cobb-Douglas and translog production functions to calculate total factor productivity (TFP) in Pakistan over the period 1985 – 2005, first for the manufacturing and agricultural sectors individually, then for the economy as a whole. In manufacturing, productivity increased at an average of 2.4% per year with output growth being driven mainly by increases in capital. Despite the limitations of the available agricultural data, we have determined that productivity has grown at an average rate of 1.75% per year in this sector. The major drivers of growth in agriculture have been increases in labor and TFP. These estimates of sectoral TFP put Pakistan at par or above average as compared to other developing countries, but lagging behind the East Asian economies. For the economy as a whole, TFP has increased at an average rate of only 1.1% a year in Pakistan, resulting in almost three quarters of GDP growth attributed to increases in labor and the capital stock.

In this paper, we look at the pace at which firms adjust their employment levels as a measure of “microeconomic flexibility.” Flexibility aids in creative destruction processes, where less efficient establishments recede and dynamic firms can rapidly expand. Following the techniques used by Caballero, Engel, and Micco (2004), we use firm-level data from India and Pakistan to estimate the proportion of the gap closed in a year between desired and actual employment. The results for the proportion of the gap closed for India were 0.46 in 2001 and 0.45 in 2000. For Pakistan, we estimated the proportion of the gap closed as 0.2 in 2001 and 0.53 in 2000. The results for 2001 were much lower than expected (and lower than previous estimates for both countries), possibly due to the events of 9/11. Pakistan compared favorably to India in various key sectors, including chemicals, food processing, and garments. Exporters did not seem to have a quicker speed of adjustment.

Private industrial development in Pakistan has a mixed track record. This paper presents a political economy overview of industrial development in Pakistan. Starting with an analysis of initial conditions, such as low levels of urbanization and out-migration of bourgeoisie, the paper looks at the ways in which policies were used to create advantages for elites and special interests. The paper also investigates the role of foreign aid in distorting industrial structure.

The objective of this study is twofold: (i) to estimate the equilibrium real exchange rate (RER) from a long-run perspective and calculate the degree of overvaluation for the period 1972–2007, and (ii) to test the Dutch Disease hypothesis concerning the effect of capital flows on the RER in Pakistan. Based on various macroeconomic fundamentals suggested in economic literature by Edwards (1988, 1989, 1994), Elbadawi (1994), and Montiel (1997), the equilibrium RER is estimated as a function of the terms of trade, government spending, degree of openness, workers’ remittances, foreign direct investment (FDI) flows, and foreign economic assistance. In view of this study’s long-term focus, all unsustainable and temporary flows are filtered out to obtain an accurate misalignment index. Estimation results are in line with theoretical postulations: an increase in capital flows, government spending on nontradable goods and terms of trade improvement are consistent with an appreciation of the RER, while an increase in the degree of openness is expected to depreciate the RER. Findings suggest that the RER suffers from chronic overvaluation in Pakistan. In spite of filtering out unsustainable and temporary flows, overvaluation increased from 0.75% in 2001 to 22.9% in 2007. A sharp rise in FDI flows (between 2005 and 2007) and an increase in remittances (between 2002 and 2007) are among the main factors that have contributed to this persistent overvaluation. Results also suggest that the Dutch Disease hypothesis holds in the case of Pakistan.

This paper examines the prospects of expanding bilateral trade between Pakistan and China particularly in the context of the recently signed free trade agreement between the two countries. Using the augmented gravity model in the tradition of Rose (2004), the paper shows that there is significant potential for the expansion of bilateral trade between the two countries as a result of the free trade agreement. The paper also analyzes bilateral trade flows between the two countries in terms of a trade specialization index and the Grubel-Lloyd index of intra-industry trade. We show that bilateral trade between the two countries is heavily tilted in favor of China and that this situation may persist in the short term.

This paper examines and critiques the worldwide mushrooming of preferential trading arrangements and traces its implications for Pakistan. It points out that this development is fundamentally contrary to the principle of most-favored-nation (MFN) treatment, which was the cornerstone of the post-war multilateral trading system as embodied in the General Agreement on Tariffs and Trade (GATT) and by the World Trade Organization (WTO). The causes of the rise in bilateral and regional trading arrangements are discussed and it is shown that they pose a real threat to many relatively small economies, including Pakistan. The paper discusses the various preferential trade agreements Pakistan has already signed. It notes that, with the exception of its trade agreement with China, Pakistan has not succeeded in concluding preferential trading arrangements with any of the strategically and systemically more important countries, viz., the US, European Union, and Gulf Cooperation Council (GCC). The South Asia Free Trade Area (SAFTA) could potentially be of considerable importance for Pakistan’s long-term economic growth, but this potential might not be realized if India and Pakistan fail to overcome their mutual differences. Finally, the paper explores steps that might be taken to promote Pakistan’s economic interests in its bilateral relations. It points out that, apart from achieving a measure of macroeconomic stability, Pakistan needs to improve its international competitiveness through productivity improvements and be more strategic in its trading relations. Its market access to leading industrial countries that are entering free trade agreements (FTAs) with Pakistan’s competitors is a real threat and remedial actions are required.

This paper analyzes how trade can develop between low and high wage countries when there is free trade and when there is protection. In particular, the paper focuses on Pakistani industrial development from the 1950’s and how standard international trade theory relies on specific assumptions about the nature of capital, which may not hold. This, in turn, has specific implications for industrial policy in low wage countries.

The slow pace of progress of the South Asian regional trade integration process under SAARC has prompted many countries to seek bilateral agreements. Sri Lanka is a case in point with bilateral agreements with both India and Pakistan. While the former is acknowledged to have yielded positive results, the latter has remained of limited interest. Given that India remains the single most important trading partner for almost all other South Asian countries, regionalism in South Asia essentially entails bilateral market access to India. The current evidence suggests that India has attempted to do so via a host of bilateral and regional arrangements, but that the emerging nature of that integration process is unlikely to be an ‘inclusive’ South Asian regional grouping.

Pakistan and India are the two largest economies in South Asia with very low levels of bilateral trade. This has been the result of border disputes and political tensions, but also of inward-looking import-substitution growth strategies. Trade (including official and unofficial) between the two countries stood at around US$ 2.5-2.6 billion in 2007/08 but it could potentially be as much as US$ 5-10 billion or two to four times its current levels. The Composite Dialogue Process (CDP) has led to substantial improvements in political relations over the last 5 years and trade relations have shown positive outcomes as well. This paper recommends that the process be strengthened further by restarting the stalled CDP, Pakistan granting most favored nation (MFN) status to India, continuing to reduce impediments to trade and trade logistics, and perhaps even considering the possibility of a free trade agreement (FTA) with India.

This study analyzes the role of human capital and job attributes, i.e., supply-side determinants, in determining wages in a period of trade liberalization. Using the Mincerian earning function and based on data from the Labor Force Surveys, we construct a model to estimate various wage determinants and compute the rates of return to different educational qualifications and relative occupational wage shares for the years 2005/06 and 1990/91. The estimated earning functions for 1990/91 and 2005/06 are compared to investigate whether individual characteristics—such as gender, job location, nature of job, educational qualifications, and different occupations—cause the wage gap to widen or contract under conditions of trade liberalization. The mean and quantile regression approach is used for estimation purposes. Our key findings postulate (i) an increasing gender pay gap, (ii) a higher wage premium to the highest educational qualification, and (iii) more or less stable relative wages for different occupations over time. In addition, wage dispersion across occupational groups appears more pronounced in 1990/91 than in 2005/06, implying a declining trend in the difference in wage distribution across occupations. Our findings suggest that trade liberalization cannot be presumed to pose a threat to the labor market in the wage context. However, exposing labor to an open market has not increased the productivity and skills of labor or helped reap the potential benefits of trade liberalization.
